Review

An engineer who wants to document an electric circuit would create which of the following?

67% Answer Correctly

	a schematic
	a blueprint
	a matrix
	a layout

Solution

A schematic is the proper name for a drawing of an electric or electronic circuit.

This circuit component symbol represents a(n):

57% Answer Correctly

	transformer
	AC source
	capacitor
	DC source

Solution

Direct current flows in only one direction in a circuit, from the negative terminal of the voltage source to the positive. A common source of direct current (DC) is a battery.

The watt is a unit of measurement for:

78% Answer Correctly

	resistance
	power
	frequency
	energy

Solution

Electrical power is measured in watts (W) and is calculated by multiplying the voltage (V) applied to a circuit by the resulting current (I) that flows in the circuit: P = IV. In addition to measuring production capacity, power also measures the rate of energy consumption and many loads are rated for their consumption capacity. For example, a 60W lightbulb utilizes 60W of energy to produce the equivalent of 60W of heat and light energy.

Why is an insulator a poor conductor of electricity?

68% Answer Correctly

	an insulator has few free electrons
	an insulator is made of inorganic material
	an insulator is made of organic material
	an insulator has many free electrons

Solution

Insulators have valence shells that are more than half full of electrons and, as such, are tightly bound to the nucleus and difficult to move from one atom to another.

A capacitor to an electronic circuit is like a _______________ to a house?

67% Answer Correctly

	storage shed
	safe
	gate
	driveway

Solution

Capacitors store electricity and are used in circuits as temporary batteries. Capacitors are charged by DC current (AC current passes through a capacitor) and that stored charge can later be dissipated into the circuit as needed. Capacitors are often used to maintain power within a system when it is disconnected from its primary power source or to smooth out or filter voltage within a circuit.
